Embodiment
In order that those skilled in the art more fully understand technical scheme, it is right with reference to the accompanying drawing of the present invention Technical scheme carries out clear, complete description, and based on the embodiment in the application, those of ordinary skill in the art exist The other similar embodiments obtained on the premise of not making creative work, it should all belong to the scope of the application protection.
Embodiment one：
As depicted in figs. 1 and 2, a kind of printer, including installing plate 1, fixed plate 2, supply-roll 3, recovery axle 4, the and of glue stick 6 Printing portion 5, the both ends of the printing portion 5 are fixedly connected with installing plate 1 and fixed plate 2 respectively, supply-roll 3 and the one of recovery axle 4 End is arranged on installing plate 1, and untapped carbon ribbon is enclosed on supply-roll 3, and the carbon ribbon after use is reclaimed by reclaiming axle 4.Institute Printhead 51 and buffer gear that printing portion 5 includes being connected with each other are stated, the buffer gear includes fixed block 52, guide rod 53 and led Block 54, the both ends of the fixed block 52 are fixedly connected with printhead 51 and guide rod 52 respectively, and the guide rod 52 is enclosed in guide block 54, The external diameter of guide rod 52 is less than the internal diameter of guide block 54, i.e. guide rod 52 weak vibrations, guide block 54 can be fixed on printing in guide block 54 Be cased with the (not shown) of spring one in the frame of machine, outside the guide rod 53, the both ends of the spring one respectively with fixed block 52 Offseted with guide block 54.The side of the printhead 51, fixed block 52 and guide block 54 is fixedly connected with installing plate 1, printhead 51, The opposite side of fixed block 52 and guide block 54 is fixedly connected with fixed plate 2.Deflector roll 12 and photoelectric detector are additionally provided with installing plate 1 13, deflector roll 12 is used for the track for supporting and limiting carbon ribbon, and deflector roll 12 is provided with 3, and photoelectric detector 13 is located therein 2 deflector rolls 12 Between, for detect carbon ribbon whether normal work, if be finished.
As shown in Figure 3 and Figure 4, the printer also includes rotating part, and installing plate 1 is provided with rotating hole 11, the rotation Portion is fixedly connected with the installing plate 1, drives the installing plate 1 to rotate by the rotating part, so as to drive on installing plate 1 Printing portion 5 rotates, and realizes contact of the printhead 51 with glue stick 6.Printhead 51 and glue stick 6 all have certain length, are processing When printhead 51 and glue stick 6, if there is certain mismachining tolerance, printhead 51 and glue stick 6 is often caused all to paste Close, might have the part not fit together, in this case, if without buffer gear, the result printed can not Entirely, cause certain waste, the present invention due to guide rod 53 can in guide block 54 weak vibrations so that printhead 51 has one The fixed free degree, even if ensureing in the case of mismachining tolerance being present, printhead 51 can be also bonded comprehensively with glue stick 6.The rotation Portion includes rotary shaft, rotary shaft 73 and cam 71, and the cam 71 is connected with motor 72, and the rotary shaft 73 is fixed on installing plate On 1, and with cam 71 against the rotary shaft passes through the rotating hole 11 of installing plate 1, and is flexibly connected with frame.The rotation Transfer part also includes bearing 1, and the bearing 1 is sleeved on the outside of rotary shaft 73, if do not installed bearing 1, rotary shaft 73 It is sliding friction with the outer surface of cam 71, coefficient of friction is larger, and the abrasion of cam 71 and rotary shaft 73 is all more serious, installation axle It is rolling friction after holding 1, between bearing 1 and cam 71, reduces the mill of cam 71, bearing 1 and rotary shaft 73 Damage.Motor 72 rotates with moving cam 71, then realizes that installing plate 1 rotates around rotary shaft by bearing 1 and rotary shaft 73, when beating When print first 51 fits together with glue stick 6, motor 72 stops operating, and printhead 51 is started working, when unexpected power-off or other When emergency occurs, cam 71 recovers the position to before rotating, and installing plate 1 falls after rise under gravity, makes printhead 51 Separated with glue stick 6.
As shown in Figure 5 and Figure 6, the supply-roll 3 includes shaft body 31, axle sleeve 32, bearing 2 38, spring 2 42, resilience Block 39, stop sleeve 33, clamping sleeve 34, spring 3 36 and top cover 35, the axle sleeve 32, bearing 2 38 and resilience block 39 are sequentially sleeved in In shaft body 31, the bearing 2 38 is arranged on installing plate 1, and the resilience block 39 is fixedly connected with shaft body 31, the bullet The both ends of spring 2 42 are fixedly connected with bearing 2 38 and resilience block 39 respectively.The shaft body 31 is provided with ring flange, the axle sleeve 32 offset with ring flange, and one end of clamping sleeve 34 also is provided with ring flange, and the clamping sleeve 34 is enclosed in shaft body 31, and with axle sheet Body 31 is fixedly connected, and the top cover 35, spring 3 36 and stop sleeve 33 are sequentially sleeved on clamping sleeve 34, the stop sleeve 33 and institute State axle sleeve 32 to offset, the top cover 35 is threadedly coupled with the clamping sleeve 34.Between the spring 3 36 and the stop sleeve 33 Friction plate 37 is additionally provided with, friction plate 37 is used to protect the parts surface contacted with spring, avoids parts surface from being scratched.Use When, carbon ribbon is enclosed on the outside of axle sleeve 32, when carbon ribbon is pulled rotation, usually because inertia causes carbon ribbon to rotate excessively, makes carbon Band can not be in tensioning state all the time.The present invention supply-roll 3 when in use, due to having frictional force between axle sleeve 32 and carbon ribbon, Axle sleeve 32 can also rotate with carbon ribbon, while frictional force between shaft body 31 and stop sleeve 33 and axle sleeve 32 all be present, and return Bullet block 39 connects as one with shaft body 31, so shaft body 31 and resilience block 39 can also rotate, due to spring 2 42 Both ends are separately fixed on bearing 2 38 and resilience block 39, and bearing 2 38 is fixed on installing plate 1, and bearing 2 38 will not occur Rotate, therefore spring 2 42 is in extended state after the rotation of resilience block 39.After carbon ribbon and axle sleeve 32 stop operating, in bullet Under the pulling force effect of spring 2 42, resilience block 39 and shaft body 31 rotate backward, so as to drive axle sleeve 32 and carbon ribbon also reverse Rotate, carbon ribbon is in tensioning state all the time.The both ends of spring 3 36 offset with stop sleeve 33 and top cover 35 respectively, axle sleeve 32 Both ends are mutually close to stop sleeve 33 and the ring flange of shaft body 31 respectively, and the compression journey of spring 3 36 is adjusted by turning top cover 35 Degree, the frictional force between axle sleeve 32 and shaft body 31 is adjusted, finally realize that shaft body 31 and axle sleeve 32 drive carbon ribbon resilience, and The dynamics of resilience is just right, can either be tensioned carbon ribbon, is unlikely to break carbon ribbon again.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each embodiment is only wrapped Containing an independent technical scheme, this narrating mode of specification is only that those skilled in the art should for clarity Using specification as an entirety, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art It is appreciated that other embodiment.
